Description

Technical Field

[0001] This utility model relates to the field of light-emitting devices for road traffic safety, specifically to a brightening and luminous raised solar-powered buried road stud. Technical Background

[0002] Solar-powered luminous road studs, also known as raised solar-powered luminous road markers or solar ground lights, are mainly installed on road surfaces or the ground to provide luminous guidance for drivers of motor vehicles and can also serve as auxiliary lighting equipment.

[0003] The in-ground solar-powered road studs are less susceptible to damage from vehicle impacts and crushing because the main body is buried in the road surface during installation. They also have a large internal space and can be expanded with multiple functions (for example, there is redundant space to install a larger battery or add intelligent control circuits). However, the exposed part at the top is low, and sometimes the light is blocked by the surrounding area after the road surface sinks due to vehicle crushing, which affects the light emission distance.

[0004] Someone has proposed a solar-powered luminous glass road stud by imitating the shape of reflective glass road studs. During installation, the buried part below the ground reference plane is buried in the road surface or ground, while the raised top below the ground reference plane is exposed on the road surface or ground. An LED main light source is set side by side in the cavity below the raised top, facing the front and back, and its main beam is focused at a small elevation angle and emitted in the front and back.

[0005] This type of solar-powered luminous glass road stud has the following very obvious drawbacks:

[0006] Its light emission brightness is low, the viewing distance is short, and the light emission angle is difficult to control. The light emission function is limited. In particular, the setting of its LED light source is mainly designed to facilitate the observation of motor vehicle drivers. The elevation angle of the main beam of its LED light source varies with the distance and there is a certain degree of brightness loss at a certain angle, resulting in poor lighting effect for non-motor vehicle drivers and pedestrians.

[0007] In summary, the simple structure of this type of solar-powered luminous glass road stud results in unsatisfactory luminous effects. Especially with the shift in current traffic concepts, the service target of road studs has expanded from motor vehicle drivers to include non-motorized vehicle drivers and pedestrians, placing new and higher demands on the luminous effects of road studs. This type of solar-powered luminous glass road stud can no longer meet these requirements. Therefore, improving the luminous brightness of this type of road stud, ensuring a complete viewing angle (elevation angle) without blind spots for pedestrians, and facilitating intelligent control and multimodal or multifunctional luminescence, has become an urgent priority. Utility Model Content

[0008] In view of the limitations of existing technologies and the new demands of industry development, the technical problem to be solved by this utility model is to provide a brightening and luminous raised solar-powered underground road stud that provides superior luminous effect for motor vehicle drivers, non-motor vehicle drivers and pedestrians. This technology not only improves the luminous brightness, but also facilitates multi-mode luminescence and adapts to intelligent control requirements, thus better meeting the new demands of the transportation industry.

[0009] This utility model designs a unique optical housing structure, which can use tempered glass or transparent plastic as the transparent optical housing. Combining material molding process, luminescence and optics, and combining optical structure and assembly structure for optical matching, the transparent optical housing is a hollow transparent protrusion formed by the bottom transparent base shell and the top central part bulging upward to form a small upper part and a large lower part. It has a cavity with an opening facing downward and the top central part bulging upward, which is roughly similar in shape to the transparent optical housing (1). The overall structure is a cavity-shaped transparent housing structure with a small upper part and a large lower part (the cross-section is similar to the shape of a convex character) and a central symmetry. Matching transparent optical optics are respectively set in its cavity. The central LED light source group and the peripheral LED light source group in the shell optical structure form a combination of high and low light emission zones and inner and outer zones, creating a three-dimensional light emission effect that combines points (multiple LEDs in the central LED light source group are relatively concentrated) and surfaces (multiple LEDs in the peripheral LED light source group are relatively distributed). The light emitted from the peripheral LED light source group compensates for the brightness and angle of the light emitted from the central LED light source group, improving the overall light emission brightness. This allows for a larger light emission area for close-range observation, which is beneficial for non-motorized vehicle drivers and pedestrians. The long-range light emission distance is also longer, which is beneficial for motorized vehicle drivers. Furthermore, it facilitates the realization of various controllable light emission effects such as dual-group dual-control and color switching.

[0010] Furthermore, multiple long-afterglow emitters can be installed above the peripheral LED light source group. The peripheral LED light source group can excite the long-afterglow emitters to emit afterglow light, thereby realizing the long-afterglow light induction function or long-afterglow light indication function, which can improve the visibility for non-motorized vehicle drivers or pedestrians.

[0011] The specific implementation scheme of this utility model is as follows: a brightening and luminous raised solar underground road stud, comprising a transparent optical shell (1), an inner support body (2), a high-position (relatively high-position) light source group (3), a photovoltaic device (5), an energy storage element (6), a control drive circuit (7), and a curing body of encapsulant (8).

[0012] The transparent optical housing (1) is a hollow transparent base shell (1B) with a downward opening and surrounding wall (also called the buried shell, which is buried in the ground during installation). The central part of the top of the shell is raised upward and the inner top wall is concave upward to form a hollow transparent protrusion (1A) with a smaller top and a larger bottom. The non-protruding part forms an outer ring surface (1B-a1) around the bottom of the transparent protrusion (1A) (its height corresponds to the buried reference plane, and after installation, it roughly corresponds to the road surface height). It is a centrally symmetrical cavity transparent shell structure with a receiving cavity (1-q) (the overall shape is smaller at the top and larger at the bottom, and the cross-section is similar to the shape of a convex character).

[0013] The outer surface (1A-b1) of the transparent protrusion (1A) is a surface of rotation about the central axis of symmetry of the transparent protrusion (1A). The outer top surface (1A-a1) of the transparent protrusion (1A), the outer surface (1A-b1) of the transparent protrusion (1A), and the outer ring surface (1B-a1) of the transparent base shell (1B) constitute the light-emitting surface of the protruding underground road stud.

[0014] The area where the transparent protrusion (1A) and the outer ring surface (1B-a1) of the transparent base shell (1B) are located is generally similar to a flying saucer or a round hat shape.

[0015] The inner support body (2) is a support layer adapted to the accommodating cavity (1-q) structure of the transparent optical shell (1), and is combined in the accommodating cavity (1-q) of the transparent base shell (1B), forming an air layer between the inner support body (2) and the transparent optical shell (1) above it [that is, air layers are respectively provided around the central LED light source group (3) and the peripheral LED light source group (4)].

[0016] The photovoltaic device (5) has multiple photovoltaic cells arranged in a modular fashion around the central axis of symmetry of the transparent protrusion (1A), with a central empty space [which can be used to set the central LED light source group (3)] on the inner support body (2) [preferably located near the lower part of the outer ring surface (1B-a1)] and connected in series and / or parallel circuits.

[0018] The peripheral (projection periphery from above) area of ​​the central LED light source group (3) is also provided with a low-position (relatively low, installation height relative to the central LED light source group) light source group (4). The peripheral LED light source group (4) is composed of multiple LEDs, which are arranged at multiple points at intervals around the receiving cavity (1-q) of the transparent base shell (1B) on the area of ​​the photovoltaic cell without photovoltaic device (5) from above [preferably on the circuit board of the photovoltaic cell without photovoltaic device (5) or on the inner support body (2) of the photovoltaic cell without photovoltaic device (5)].

[0019] The energy storage element (6) and control drive circuit (7) are installed inside or under the inner support body (2). The central LED light source group (3), the peripheral LED light source group (4), the photovoltaic device (5), the energy storage element (6), and the control drive circuit (7) are connected to form a circuit.

[0020] The inner support body (2) is provided with a curing body (8) for encapsulating adhesive below it. The inner support body (2), the central LED light source group (3), the photovoltaic device (5), the energy storage element (6), and the control drive circuit (7) are encapsulated in a transparent optical shell (1). This forms a raised solar underground road stud with a waterproof encapsulation structure, which matches (or compensates) the emitted light of the outer LED light source group (4) and the central LED light source group (3) according to the emission area (high and low area, inner and outer area), emission angle, and emission brightness.

[0021] The LED of the central LED light source group (3) is matched with the optical structures of its inner side surface (1A-b2) and outer side surface (1A-b1) in front of it to form an LED optical matching structure in which the emitted light after passing through the outer side surface (1A-b1) is focused and emitted in a horizontal or deviated horizontal direction. The LED of the peripheral LED light source group (4) is matched with the optical structure of the transparent optical shell (1) to form an LED optical matching structure in which the emitted light after passing through the transparent optical shell (1) is refracted, reflected or totally reflected and emitted from its outer top surface (1A-a1), outer side surface (1A-b1) and outer ring surface (1B-a1) respectively.

[0022] Furthermore, the main structure of the transparent protrusion (1A) (ignoring some details or removing some auxiliary structures) is a transparent optical part formed by rotating around a central axis of symmetry. The outer surface (1A-b1) of the transparent protrusion (1A) is a surface of revolution formed by rotating a quadratic curve around its central axis of symmetry, or a surface of revolution formed by rotating a fitted curve of a quadratic curve around its central axis of symmetry.

The curved transition section not only plays a transition buffer role and increases the structural strength of the shell against wheel crushing or impact, but is also an important component involved in optical structure matching.

[0024] Furthermore, the central LED light source group (3) includes at least two sets of LEDs arranged back-to-back with their light emission directions facing forward and backward, respectively; or at least two sets of LEDs arranged opposite each other with their light emission directions facing forward and backward, respectively; or at least two sets of LEDs arranged crosswise with their light emission directions facing forward and backward, respectively.

[0026] Among them, the main beam (L3) of the LED in the central LED light source group (3) is incident from the inner side surface (1A-b2) in front of it, and after refraction, it is displaced upward and then refracted from the outer side surface (1A-b1) before exiting to the side front. The beam (L4-1) emitted by the LED in the peripheral LED light source group (4) located on the same side as the LED in the central LED light source group (3) is incident from the inner ring surface (1B-a2) above it and exits from the outer side. The light is refracted by the surrounding surface (1B-a1) and then emitted towards the side front of the LED, forming brightness and angle compensation with the light emitted by the central LED light source group (3) on the same side along the vertical plane of the central axis of symmetry. [According to the principle of reversible light path, the central LED light source group (3) on the front side and the peripheral LED light source group (4) on the same side can be seen emitting light in front of the spike, and the central LED light source group (3) on the rear side and the peripheral LED light source group (4) on the same side can be seen emitting light behind the spike.]

It is then refracted from the outer side surface (1A-b1) on the opposite side of the LED and exits in front of the opposite side of the LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (3) on the opposite side along the vertical plane where the central axis of symmetry is located. [According to the principle of reversible light path, the central LED light source group (3) on its rear side and the peripheral LED light source group (4) on the same side can be seen emitting light in front of the road spike, and the central LED light source group (3) on its front side and the peripheral LED light source group (4) on the same side can be seen emitting light behind the road spike.]

[0122] Embodiments of this utility model are described in conjunction with the accompanying drawings.

[0123] Example 1

[0124] A type of brightening and luminous raised solar-powered underground road stud includes a transparent optical shell (110), an inner support body (120), a central LED light source group (130), a peripheral LED light source group (140), a photovoltaic device (150), an energy storage element (160), a control and drive circuit (170), and a curable encapsulant body (180). Figure 4-8 As shown.

[0125] The transparent optical housing (110) is a hollow transparent protrusion (110A) formed by the upward bulging of the central part of the bottom transparent base shell (110B) and the top of the top, which is smaller at the top and larger at the bottom. It has a cavity (110-q) with an opening facing downward and the top central part bulging upward, which is smaller at the top and larger at the bottom and has a shape that is roughly similar to that of the transparent optical housing (110). It is a cavity-shaped transparent PC injection molded housing structure or a cavity-shaped transparent tempered glass molded housing structure that is smaller at the top and larger at the bottom and centrally symmetrical.

[0126] The main structure of the transparent protrusion (110A) is a spherical table. The height (Ha) of the transparent protrusion (110A) is about 20mm. The top surface (110A-a1) of the transparent protrusion (110A) is a plane or arc surface with a radius (Ra) of about 18mm. The outer side surface (110A-b1) of the transparent protrusion (110A) is a spherical surface formed by rotating an arc around its central axis. The bottom outline of the transparent protrusion (110A) is a circle with an outer diameter (Rb) of about 30mm. The accommodating cavity (110-q) of the transparent protrusion (110A) is similar to a spherical table cavity. The thickness of the sidewall of the transparent protrusion (110A) increases from about 8mm at the top to about 10mm at the bottom.

[0127] The main structure of the transparent base shell (110B) is similar to a cylinder. The height (Hb) of the transparent base shell (110B) is about 45mm. The top outer diameter (Rf) of the wall of the transparent base shell (110B) is slightly smaller than the bottom outer diameter (Rc) of the wall of the transparent base shell (110B). The top surface of the transparent base shell (110B) is the outer ring surface (110B-1a) surrounding the transparent protrusion (110A). The inner top surface (11) of the cavity (110-q) of the transparent protrusion (110A) is... The height difference (ΔH) between the outer ring surface (110B-a1) of the transparent base shell (110B) and the transparent base shell (110B) is controlled at about 11mm. The accommodating cavity (110-q) of the transparent base shell (110B) is similar to a cylindrical cavity. The thickness of the wall of the transparent base shell (110B) is about 13mm. The outer side (110B-b1) and the bottom surface (110B-c) of the wall of the transparent base shell (110B) are coated with a reflective paint layer (110B-f) or an aluminum-plated reflective layer (110B-f) is vapor-deposited.

[0128] The outer side (110B-b1) and bottom surface (110B-c) of the transparent base shell (110B) can be coated with a coating (1100) as needed, such as a yellow or red coating, or a coating with a sandy texture.

[0129] Furthermore, the outer side of the transparent base shell (110B) is also provided with a vertical concave-convex structure (110B-t), which can make the bond between the track spike and the mounting adhesive more secure during installation and prevent the track spike from rotating.

[0130] The inner support body (120) is an injection-molded support layer adapted to the accommodating cavity (110-q) structure of the transparent optical shell (110). It is combined with the accommodating cavity (110-q) of the transparent base shell (110B) through a positioning structure, and an air layer is formed between the inner support body (120) and the transparent optical shell (110) above it. A white PCB board is provided on the inner support body (120). The six photovoltaic cells of the photovoltaic device (150) are arranged in a radial block pattern around the central axis of the transparent protrusion (110A) on the PCB board with a central empty space. The LED of the peripheral LED light source group (140) consists of six SMD packaged white 2835 LED beads. Each LED is set in the space between adjacent photovoltaic cell blocks on the inner support body (120) below the inner ring surface (110B-a2) around the central empty space formed by the photovoltaic cells of the photovoltaic device (150).

[0131] The central LED light source group (130) consists of 6 Lamp-packaged yellow or white F5 LED beads. Each LED is divided into two groups facing forward and backward (3 beads in each group are arranged side by side). They are fixed by high pins in the cavity (110-q) of the transparent protrusion (110A) above the central empty space formed by the photovoltaic cells of the photovoltaic device (150).

[0132] The energy storage element (160) is a lithium battery, and the control drive circuit (170) is a single-chip microcomputer control drive circuit, which is embedded under the inner support body (120). The central LED light source group (130), the peripheral LED light source group (140), the photovoltaic device (150), the energy storage element (160), and the control drive circuit (170) are connected to form a circuit by wires. Then, white epoxy resin is poured into the bottom opening of the accommodating cavity (110-q) of the transparent optical shell (110), and it is leveled and cured to form a curing body (180). The inner support body (120), the central LED light source group (130), the photovoltaic device (150), the energy storage element (160), and the control drive circuit (170) are encapsulated in the transparent optical shell (110) to form a waterproof encapsulation structure.

[0133] The main LED beam (L3) of the central LED light source group (130) is incident from its inner side (110A-b2) in front of it, and after refraction, it is displaced upward and emitted from its outer side (110A-b1) towards the side front at an elevation angle of 2° to 18°.

[0134] The light beam (L4-1) of the peripheral LED light source group (140) is incident from the inner ring surface (110B-a2) above it, refracted from the outer ring surface (110B-a1), and then emitted to the side front of the LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (130) on the same side along the vertical plane of the central axis of symmetry.

[0135] The second LED beam (L4-2) of the peripheral LED light source group (140) is incident from its inner side (110A-b2) on the opposite side, refracted from its outer side (110A-b1), and then emitted towards the side front of its opposite side. The third LED beam (L4-3) of the peripheral LED light source group (140) is incident from its inner top surface (110A-a2), refracted from its outer top surface (110A-a1), and then emitted towards the side upper side of its opposite side. The fourth LED beam (L4-4) of the peripheral LED light source group (140) is incident on the inner side (110A-b2) of the left and right sides of the LED and undergoes total internal reflection before emitting from the opposite side of the LED. The outer surface (110A-b1) refracts the light and then emits it towards the side front of the opposite LED. The light beam (L4-5) of the LED of the peripheral LED light source group (140) enters from the junction of the inner ring surface (110B-a2) and the inner surface (110B-b2) above it, is reflected by the reflective layer (110B-f) on the outer surface (110B-b1), and then enters from the inner surface (110A-b2) on the opposite side of the LED. After being refracted from the outer surface (110A-b1), it is emitted towards the side front of the opposite LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (130) on the opposite side along the vertical plane where the central axis of symmetry is located.

[0136] This allows for the formation of a brighter, luminous raised solar-powered underground road stud with a complete 180° luminous elevation angle range within the vertical plane containing at least the main beam of the central LED light source group (130).

[0137] Furthermore, the peripheral LED light source group (140) contains 6 LEDs arranged at approximately equal intervals around the area between the photovoltaic cells below the peripheral LED light source group (130). The luminous range angle of each LED is greater than 90°, thereby forming a brighter, luminous, raised solar-powered underground road stud with 360° luminous coverage around the road stud without any gaps. [In particular, the LEDs of the peripheral LED light source group (140) on the left and right sides of the road stud emit light and shoot out to the left and right respectively, which makes up for the defect that the main beam emitted by the central LED light source group (130) is only visible in front of and behind the road stud].

[0138] Furthermore, the outer top surface (110A-a1) of the transparent protrusion (110A) and the outer ring surface (110B-a1) of the transparent base shell (110B) are respectively provided with dot matrix and spoke-shaped light guide structures, which also have anti-slip function.

[0139] This utility model of a brightening and luminous raised solar-powered buried road stud has its transparent base shell below the outer ring (buried reference surface) embedded in the road edge, lane divider, or center line during installation, while the top of the transparent raised section below the buried reference surface protrudes from the road surface or ground. It primarily utilizes a combination of high and low, inner and outer LED light sources to create a three-dimensional luminous effect combining points (formed by the relatively concentrated arrangement of the central LED light source) and surfaces (formed by the distributed arrangement of multiple LEDs in the outer LED light source). The light emitted from the outer LED light source compensates for the brightness and angle of the light emitted from the central LED light source, improving overall luminous brightness. This allows for a larger luminous area for close-range observation, facilitating observation by non-motorized vehicle drivers and pedestrians, and a longer viewing distance for long-range observation, benefiting motorized vehicle drivers. Furthermore, it facilitates various controllable luminous effects such as dual-group dual-control and color switching, resulting in significant social and economic benefits.

The thickness of the sidewall of the transparent protrusion (210A) increases from about 9mm at the top to about 11mm at the bottom.

[0144] The main structure of the transparent base shell (210B) is similar to a cylinder. The height (Hb) of the transparent base shell (210B) is about 43mm.

The outer side (210B-b1) and the bottom surface (210B-c) of the wall of the transparent base shell (210B) are coated with a reflective paint layer (210B-f) or an aluminum-plated reflective layer (210B-f) is vapor-deposited.

[0145] The outer side (210B-b1) and bottom surface (210B-c) of the transparent base shell (210B) can be coated with a coating (2100) as needed, such as a yellow or red coating, or a coating with a sandy texture.

[0146] Furthermore, the outer side of the transparent base shell (210B) is also provided with a vertical concave-convex structure (210B-t), which can make the bond between the track spike and the mounting adhesive more secure during installation and prevent the track spike from rotating.

The inner ring surface (210B-a2) above the LED of the outer LED light source group (240) may also be provided with a concave groove (210k), which can be a light-diffusing structure to improve the comfort of light emission for non-motorized vehicle drivers and pedestrians.

[0148] The central LED light source group (230) consists of 6 Lamp-packaged yellow or white F5 LED beads. Each LED is arranged with its head facing outward at equal angular distances of 60° horizontal angle to form a 6-directional light emission. The LEDs are fixed by high pins in the cavity (210-q) of the transparent protrusion (210A) above the central empty space surrounded by the photovoltaic cells of the photovoltaic device (250).

[0149] The energy storage element (260) uses a lithium battery, and the control drive circuit (270) uses a single-chip microcomputer control drive circuit. It is embedded under the inner support body (220). The central LED light source group (230), the peripheral LED light source group (240), the photovoltaic device (250), the energy storage element (260), and the control drive circuit (270) are connected by wires to form a circuit. Then, white epoxy resin is poured into the bottom opening of the accommodating cavity (210-q) of the transparent optical shell (210), and it is leveled and cured to form a curing body (280). The inner support body (220), the central LED light source group (230), the photovoltaic device (250), the energy storage element (260), and the control drive circuit (270) are encapsulated in the transparent optical shell (210) to form a waterproof encapsulation structure.

[0150] The main beams (L3) of each LED in the central LED light source group (230) are incident from the inner side (210A-b2) in front of it, refracted, and displaced upwards, exiting from the outer side (210A-b1) in six directions (front, left front, right front, rear, left rear, right rear) with an elevation angle of 2° to 15°.

[0151] The light beam (L4-1) of the peripheral LED light source group (240) is incident from the inner ring surface (210B-a2) above it, refracted from the outer ring surface (210B-a1), and then emitted to the side front of the LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (230) on the same side along the vertical plane of the central axis of symmetry.

[0152] The second LED beam (L4-2) of the peripheral LED light source group (240) is incident from its inner side (210A-b2) on the opposite side, refracted from its outer side (210A-b1), and then emitted towards the side front of its opposite side. The third LED beam (L4-3) of the peripheral LED light source group (240) is incident from its inner top surface (210A-a2), refracted from its outer top surface (210A-a1), and then emitted towards the side upper side of its opposite side. The fourth LED beam (L4-4) of the peripheral LED light source group (240) is incident on the inner sides (210A-b2) of the left and right sides of the LED and undergoes total internal reflection before emitting from the opposite side of the LED. The outer surface (210A-b1) refracts the light and then emits it towards the side front of the opposite LED. The light beam (L4-5) of the LED of the peripheral LED light source group (240) enters from the junction of the inner ring surface (210B-a2) and the inner surface (210B-b2) above it, is reflected by the reflective layer (210B-f) on the outer surface (210B-b1), and then enters from the inner surface (210A-b2) on the opposite side of the LED. After being refracted from the outer surface (210A-b1), it is emitted towards the side front of the opposite LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (230) on the opposite side along the vertical plane where the central axis of symmetry is located.

[0153] This allows for the formation of a brighter, luminous raised solar-powered underground road stud with a luminous elevation range of at least 180° without any gaps in the vertical plane containing the main beam of the central LED light source group (230).

[0154] Furthermore, the peripheral LED light source group (240) contains 6 LEDs arranged at approximately equal intervals around the area between the photovoltaic cells below the peripheral LED light source group (230). The luminous range angle of each LED is greater than 120°. Thus, the LEDs of the peripheral LED light source group (240) compensate for the horizontal luminous range angle of the LEDs of the central LED light source group (230) with their horizontal luminous range angles, thereby forming a brightened, luminous, raised solar buried road stud with 360° luminous coverage around the road stud without any gaps.

[0155] Furthermore, the outer top surface (210A-a1) of the transparent protrusion (210A) and the outer ring surface (210B-a1) of the transparent base shell (210B) are respectively provided with dot matrix and spoke-shaped light guide structures, which also have anti-slip function.

[0156] This utility model of a brightening and luminous raised solar-powered underground road stud involves embedding the transparent base shell below the outer ring (buried reference surface) into the road surface or ground at road intersections (crossroads) or road forks during installation, while the top of the transparent raised section below the buried reference surface protrudes from the road surface or ground. It primarily utilizes a combination of high and low, inner and outer LED light sources to create a three-dimensional luminous effect combining points (formed by the relatively concentrated arrangement of the central LED light source) and surfaces (formed by the distributed arrangement of multiple LEDs in the outer LED light source). The light emitted from the outer LED light source compensates for the brightness and angle of the light emitted from the central LED light source, improving overall luminous brightness. This allows for a larger luminous area for close-range observation, facilitating observation by non-motorized vehicle drivers and pedestrians, and a longer viewing distance for long-range observation, benefiting motorized vehicle drivers. Furthermore, it facilitates various controllable luminous effects such as dual-group dual-control and color switching, resulting in significant social and economic benefits.

[0157] Example 3

[0158] A type of brightening and luminous raised solar-powered underground road stud includes a transparent optical shell (310), an inner support body (320), a central LED light source group (330), a peripheral LED light source group (340), a photovoltaic device (350), an energy storage element (360), a control and drive circuit (370), a curable encapsulant body (380), a bottom cover-type protective shell (390), and a long-afterglow luminescent body (3110). Figure 12-14 As shown.

[0159] The transparent optical housing (310) is a hollow transparent protrusion (310A) formed by the bottom transparent base shell (310B) and the central part of its top protruding upward, which is smaller at the top and larger at the bottom. It has a cavity (310-q) with an opening facing downward and the central part of its top protruding upward, which is smaller at the top and larger at the bottom and has a shape that is roughly similar to that of the transparent optical housing (310). It is a cavity-shaped transparent PC injection molded housing structure that is smaller at the top and larger at the bottom and centrally symmetrical.

[0160] The main structure of the transparent protrusion (310A) is a spherical table. The height (Ha) of the transparent protrusion (310A) is about 22mm. The top surface (310A-a1) of the transparent protrusion (310A) is a plane or arc surface with a radius (Ra) of about 20mm. The outer side surface (310A-b1) of the transparent protrusion (310A) is a spherical surface formed by rotating an arc around its central axis. The bottom outline of the transparent protrusion (310A) is a circle with an outer diameter (Rb) of about 35mm. The accommodating cavity (310-q) of the transparent protrusion (310A) is similar to a spherical table cavity. The thickness of the sidewall of the transparent protrusion (310A) increases from about 9mm at the top to about 12mm at the bottom.

[0161] The main structure of the transparent base shell (310B) is similar to a cylinder. The height (Hb) of the transparent base shell (310B) is about 45mm. The top outer diameter (Rf) of the wall of the transparent base shell (310B) is approximately equal to the bottom outer diameter (Rc) of the wall of the transparent base shell (310B). The top surface of the transparent base shell (310B) is the outer ring surface (310B-a1) surrounding the transparent protrusion (310A). The inner top surface (310A-a2) of the cavity (310-q) of the transparent protrusion (310A) is larger than that of the transparent base shell (310B). The height difference (ΔH) of the outer ring surface (310B-a1) of the transparent base shell (310B) is controlled at about 11mm. The accommodating cavity (310-q) of the transparent base shell (310B) is similar to a cylindrical cavity. The thickness of the wall of the transparent base shell (310B) is about 13mm. The outer side (310B-b1) and the bottom surface (310B-c) of the wall of the transparent base shell (310B) are sprayed with a reflective paint layer (310B-f) or deposited with an aluminum reflective layer (310B-f). The bottom inner circumference of the wall of the transparent base shell (310B) is provided with a ring-shaped inner step structure (310j).

[0162] The outer side (310B-b1) and bottom surface (310B-c) of the transparent base shell (310B) can be coated with a coating (3100) as needed, such as a yellow or red coating, or a coating with a sandy texture.

[0163] Furthermore, the outer side of the transparent base shell (310B) is also provided with a vertical concave-convex structure (310B-t), which can make the bond between the track spike and the mounting adhesive more secure during installation and prevent the track spike from rotating.

[0164] The inner support body (320) is a PCB board support layer adapted to the accommodating cavity (310-q) structure of the transparent optical shell (310) (i.e., the PCB board acts as the inner support). It is combined with the accommodating cavity (310-q) of the transparent base shell (310B) through a positioning structure, and an air layer is formed between the inner support body (320) and the transparent optical shell (310) above it. The six photovoltaic cells of the photovoltaic device (350) are arranged in a radial, modular pattern around the central axis of the transparent protrusion (310A) on the PCB board with a central empty space. The LEDs of the peripheral LED light source group (340) are six SMD-packaged blue 2835 LED beads and six SMD-packaged white 2 Six SMD-packaged blue 2835 LED beads are positioned around the central space formed by the photovoltaic cells of the photovoltaic device (350) on the PCB board below the inner ring surface (310B-a2) between adjacent photovoltaic cell blocks. Six SMD-packaged white 2835 LED beads are positioned around the central axis on the edge of the central space formed by the photovoltaic cells. The inner ring surface (310B-a2) above the blue 2835 LED beads of the outer LED light source group (340) also has a recessed groove (310k) which serves as a light-diffusing structure, improving the visual comfort of non-motorized vehicle drivers and pedestrians.

[0165] Furthermore, the aforementioned groove (310k) is an annular groove. The transparent optical shell (310) is inverted, and a mixture of long-afterglow luminescent powder and transparent epoxy resin is poured into the annular groove and leveled and cured to form a long-afterglow luminescent body (3110). The blue 2835 LED beads of the peripheral LED light source group (340) below it can be controlled to emit light at a certain period and duty cycle to excite the long-afterglow luminescent body (3110) to emit afterglow light.

[0166] The central LED light source group (330) consists of 6 Lamp-packaged yellow or white F5 LED beads. Each LED is divided into two groups facing forward and backward (3 beads in each group are arranged side by side). They are fixed by high pins in the cavity (310-q) of the transparent protrusion (310A) above the central empty space formed by the photovoltaic cells of the photovoltaic device (350).

[0167] The energy storage element (360) uses a lithium battery, and the control drive circuit (370) uses a single-chip microcomputer control drive circuit. These components are embedded below the inner support body (320). The central LED light source group (330), the peripheral LED light source group (340), the photovoltaic device (350), the energy storage element (360), and the control drive circuit (370) are connected by wires to form a circuit. Then, a bottom cover-type protective shell (390) with an outer diameter smaller than the outer diameter of the transparent base shell (310B) and equipped with potting holes is formed. The structure is ultrasonically welded to the inner stepped structure (310j) of the transparent optical housing (310). White epoxy resin is then injected through the potting hole of the bottom cover type protective shell (390), and leveled and cured to form a curing body (380). The inner support body (320), the central LED light source group (330), the photovoltaic device (350), the energy storage element (360), and the control drive circuit (370) are encapsulated in the transparent optical housing (310) to form a waterproof encapsulation structure.

[0168] The main beam (L3) of the central LED light source group (330) is incident from its inner side (310A-b2) in front of it. After being refracted, the main beam is deflected downward and emitted from its outer side (310A-b1) towards the side front at an elevation angle of 2° to 25°.

[0169] The light beam (L4-1) of the peripheral LED light source group (340) is incident from the inner ring surface (310B-a2) above its side, refracted from the outer ring surface (310B-a1), and then emitted towards the side front of the LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (330) on the same side along the vertical plane of the central axis of symmetry.

[0170] The second LED beam (L4-2) of the peripheral LED light source group (340) is incident from its inner side (310A-b2) on the opposite side, refracted from its outer side (310A-b1), and then emitted towards the side front of its opposite side. The third LED beam (L4-3) of the peripheral LED light source group (340) is incident from its inner top surface (310A-a2), refracted from its outer top surface (310A-a1), and then emitted towards the side upper side of its opposite side. The fourth LED beam (L4-4) of the peripheral LED light source group (340) is incident on the inner side (310A-b2) of the left and right sides of the LED and undergoes total internal reflection before emitting from the opposite side of the LED. The outer surface (310A-b1) refracts the light and then emits it towards the side front of the LED opposite to it. The light beam (L4-5) of the LED of the peripheral LED light source group (340) enters from the junction of the inner ring surface (310B-a2) and the inner surface (310B-b2) above it, is reflected by the reflective layer (310B-f) on the outer surface (310B-b1), and then enters from the inner surface (310A-b2) opposite to the LED. After being refracted from the outer surface (310A-b1), it is emitted towards the side front of the LED opposite to it. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (330) on the opposite side along the vertical plane where the central axis of symmetry is located.

[0171] This allows for the formation of a brighter, luminous raised solar-powered underground road stud with a complete 180° luminous elevation range within the vertical plane containing at least the main beam of the central LED light source group (330).

[0172] Furthermore, the peripheral LED light source group (340) contains 12 LEDs, which are arranged at approximately equal intervals around the central LED light source group (330) in the area between the photovoltaic power generation sheets and on the edge of the central empty space enclosed by the photovoltaic power generation sheets. The luminous range angle of each LED is greater than 120°, thereby forming a brightening and luminous raised solar buried road stud with 360° luminous coverage around the road stud without any gaps.

[0173] Furthermore, the outer top surface (310A-a1) of the transparent protrusion (310A) and the outer ring surface (310B-a1) of the transparent base shell (310B) are respectively provided with dot matrix and spoke-shaped light guide structures, which also have anti-slip function.

[0174] This utility model of a brightening and luminous raised solar-powered underground road stud involves embedding the transparent base shell below the outer ring (buried reference surface) into the road edge, lane divider, or center line during installation, while the top of the transparent raised section below the buried reference surface protrudes from the road surface or ground. It primarily utilizes a combination of high and low, inner and outer LED light sources to create a three-dimensional luminous effect, combining points (formed by the relatively concentrated arrangement of the central LED light source) and surfaces (formed by the distributed arrangement of multiple LEDs in the outer LED light source). The outer LED light source compensates for the brightness and angle of the central LED light source, enhancing overall luminous brightness. Combined with long-afterglow luminescent elements, it allows for a larger luminous area for close-range observation, facilitating observation by non-motorized vehicle drivers and pedestrians, and a longer viewing distance for motorized vehicle drivers. Furthermore, it facilitates various controllable luminous effects such as dual-group dual-control and color switching, resulting in significant social and economic benefits.

[0175] Example 4

[0176] A type of brightening and luminous raised solar-powered underground road stud includes a transparent optical shell (410), an inner support body (420), a central LED light source group (430), a peripheral LED light source group (440), a photovoltaic device (450), an energy storage element (460), a control and drive circuit (470), a curable encapsulant body (480), and a bottom cover-type protective shell (490).

[0177] Long-afterglow luminescent material (4110), such as Figure 15-18 As shown.

[0178] The transparent optical housing (410) is a hollow transparent protrusion (410A) formed by the bottom transparent base shell (410B) and the central part of its top protruding upwards, which is smaller at the top and larger at the bottom. It has a cavity (410-q) with an opening facing downwards and a central part of its top protruding upwards, which is smaller at the top and larger at the bottom, and is roughly similar in shape to the transparent optical housing (410). It is a cavity-shaped transparent PC injection molded housing structure that is smaller at the top and larger at the bottom and centrally symmetrical.

[0179] The main structure of the transparent protrusion (410A) is a spherical table. The height (Ha) of the transparent protrusion (410A) is about 20mm. The outer top surface (410A-a1) of the transparent protrusion (410A) is a plane or arc surface with a radius (Ra) of about 18mm. The outer side surface (410A-b1) of the transparent protrusion (410A) is a spherical surface formed by rotating an arc around its central axis. The bottom outline of the transparent protrusion (410A) is a circle with an outer diameter (Rb) of about 33mm. The accommodating cavity (410-q) of the transparent protrusion (410A) is similar to a spherical table cavity. The thickness of the sidewall of the transparent protrusion (410A) increases from about 8mm at the top to about 11mm at the bottom.

[0180] The main structure of the transparent base shell (410B) is similar to a cylinder. The height (Hb) of the transparent base shell (410B) is approximately 42mm. The top outer diameter (Rf) of the wall surrounding the transparent base shell (410B) is approximately equal to the bottom outer diameter (Rc) of the wall surrounding the transparent base shell (410B). The top surface of the transparent base shell (410B) is the outer ring surface (410B-a1) surrounding the transparent protrusion (410A). The accommodating cavity (410-q) of the transparent protrusion (410A) is... The height difference (ΔH) between the inner top surface (410A-a2) and the outer ring surface (410B-a1) of the transparent base shell (410B) is controlled at about 10mm. The accommodating cavity (410-q) of the transparent base shell (410B) is similar to a cylindrical cavity. The thickness of the wall of the transparent base shell (410B) is about 12.5mm. The outer side surface (410B-b1) of the wall of the transparent base shell (410B) is sprayed with a reflective paint layer (410B-f) or deposited with an aluminum-plated reflective layer (410B-f).

[0181] Furthermore, the outer side of the transparent base shell (410B) is also provided with a vertical concave-convex structure (410B-t), which can make the bond between the track spike and the mounting adhesive more secure during installation and prevent the track spike from rotating.

[0182] Furthermore, six inwardly protruding reinforcing ribs (410B-z) are equidistantly arranged on the inner side surface (410B-b1) of the transparent base shell (410B), which serve to prevent displacement and rotation of the inner support body (420) and the devices thereon that are connected to it.

[0183] The inner support body (420) is an injection-molded transparent support layer with a centrally convex upward projection, adapted to the structure of the accommodating cavity (410-q) of the transparent optical shell (410). It is attached to the accommodating cavity (410-q) of the transparent base shell (410B) via a positioning structure, forming an air layer between the inner support body (420) and the upper transparent optical shell (410). A white PCB board is mounted on the inner support body (420). The 12 photovoltaic cells of the photovoltaic device (450) are arranged in a radial, modular pattern around the central axis of the transparent protrusion (410A) on the PCB board with a central empty space. The peripheral LED light source group (440) has 12 SMD packaged white 2835 LED beads. Each LED is located in the space between adjacent photovoltaic cell blocks on the PCB board below the inner ring surface (410B-a2) of the photovoltaic device (450) surrounding the central space formed by the photovoltaic cells. The inner ring surface (410B-a2) above the LEDs of the peripheral LED light source group (440) also has 6 slots (410k) spaced apart, which can be a light-diffusing structure to improve the comfort of light emission for non-motorized vehicle drivers and pedestrians.

[0184] Furthermore, the aforementioned slot (410k) is a circular hole. The transparent optical housing (410) is inverted, and a mixture of long-afterglow luminescent powder and transparent epoxy resin is poured into the circular hole and leveled and cured to form (12 / 2 = 6) long-afterglow luminescent bodies (4110). The six SMD-packaged white 2835 LED beads of the peripheral LED light source group (440) below can be controlled to emit light at a certain period and duty cycle, exciting the long-afterglow luminescent bodies (4110) to emit afterglow light. The six SMD-packaged white 2835 LED beads of the peripheral LED light source group (440) above, which do not have long-afterglow luminescent bodies, can emit light directly from their top surface (410A-a1), outer side surface (410A-b1), and outer ring surface (410B-a1).

[0185] The central LED light source group (430) consists of 6 Lamp-packaged white F5 LED beads. Each LED is divided into two groups (3 beads in each group) facing forward and backward, and is fixed on the upper protrusion of the inner support body (420) in the cavity (410-q) of the transparent protrusion (410A) above the central empty space formed by the photovoltaic cells of the photovoltaic device (450).

[0186] The energy storage element (460) uses a lithium battery, and the control drive circuit (470) uses a single-chip microcomputer control drive circuit. It is embedded under the inner support body (420). The central LED light source group (430), the peripheral LED light source group (440), the photovoltaic device (450), the energy storage element (460), and the control drive circuit (470) are connected to form a circuit by wires. Then, the bottom cover type protective shell (490) with the glue filling hole is combined to the bottom of the transparent optical shell (410) by ultrasonic welding. Then, white epoxy glue is poured into the glue filling hole of the bottom cover type protective shell (490), and it is leveled and cured to form a sealed glue cured molded body (480). The inner support body (420), the central LED light source group (430), the photovoltaic device (450), the energy storage element (460), and the control drive circuit (470) are encapsulated in the transparent optical shell (410) to form a waterproof encapsulation structure.

[0187] The main beam (L3) of the central LED light source group (430) is incident from the inner side (410A-b2) in front of it. After being refracted, the main beam is displaced upward and emitted from the outer side (410A-b1) towards the side front at an elevation angle of about 1° to 8° (approximately horizontal).

[0188] The light beam (L4-1) of the peripheral LED light source group (440) is incident from the inner ring surface (410B-a2) above its side, refracted from the outer ring surface (410B-a1), and then emitted towards the side front of the LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (430) on the same side along the vertical plane of the central axis of symmetry.

[0189] The second LED beam (L4-2) of the peripheral LED light source group (440) is incident from its inner side (410A-b2) on the opposite side, refracted from its outer side (410A-b1), and then emitted towards the side front of its opposite side. The third LED beam (L4-3) of the peripheral LED light source group (440) is incident from its inner top surface (410A-a2), refracted from its outer top surface (410A-a1), and then emitted towards the side upper side of its opposite side. The fourth LED beam (L4-4) of the peripheral LED light source group (440) is incident on the inner side (410A-b2) of the left and right sides of the LED and undergoes total internal reflection before emitting from the opposite side of the LED. The outer surface (410A-b1) refracts the light and then emits it towards the side front of the opposite LED. The light beam (L4-5) of the LED of the peripheral LED light source group (440) enters from the junction of the inner ring surface (410B-a2) and the inner surface (410B-b2) above it, is reflected by the reflective layer (410B-f) on the outer surface (410B-b1), and then enters from the inner surface (410A-b2) on the opposite side of the LED. After being refracted from the outer surface (410A-b1), it is emitted towards the side front of the opposite LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (430) on the opposite side along the vertical plane where the central axis of symmetry is located.

[0190] This allows for the formation of a brighter, luminous raised solar-powered underground road stud with a luminous elevation range of at least 180° without any gaps in the vertical plane containing the main beam of the central LED light source group (430).

[0191] Furthermore, the peripheral LED light source group (440) contains 12 LEDs, which are arranged at approximately equal intervals around the area between the photovoltaic power generation cells below the peripheral LED light source group (430). The luminous range angle of each LED is greater than 120°, thereby forming a brightening and luminous raised solar buried road stud with 360° luminous coverage around the road stud without any gaps.

[0192] Furthermore, the outer top surface (410A-a1) of the transparent protrusion (410A) and the outer ring surface (410B-a1) of the transparent base shell (410B) are respectively provided with dot matrix and spoke-shaped light guide structures, which also have anti-slip function.

[0193] This utility model of a brightening and luminous raised solar-powered underground road stud involves embedding the transparent base shell below the outer ring (buried reference surface) into the road edge, lane divider, or center line during installation, while the top of the transparent raised section below the buried reference surface protrudes from the road surface or ground.

[0195] A type of brightening and luminous raised solar-powered underground road stud includes a transparent optical shell (510), an inner support body (520), a central LED light source group (530), a peripheral LED light source group (540), a photovoltaic device (550), an energy storage element (560), a control and drive circuit (570), a curable encapsulant body (580), and a long-afterglow luminescent body (5110). Figure 19-23 As shown.

[0196] The transparent optical housing (510) is a hollow transparent protrusion (510A) formed by the upward bulging of the central part of the bottom transparent base shell (510B) and the top of the top, which is smaller at the top and larger at the bottom. It has a cavity (510-q) with an opening facing downward and the top central part bulging upward, which is smaller at the top and larger at the bottom and has a shape that is roughly similar to that of the transparent optical housing (510). It is a cavity-shaped transparent PC injection molded housing structure or a cavity-shaped transparent tempered glass molded housing structure that is smaller at the top and larger at the bottom and centrally symmetrical.

[0199] Furthermore, the outer side of the transparent base shell (510B) is also provided with a vertical concave-convex structure (510B-t), which can make the bond between the track spike and the mounting adhesive more secure during installation and prevent the track spike from rotating.

[0200] The inner support body (520) is an injection-molded transparent support layer with a centrally convex upward projection that is adapted to the structure of the accommodating cavity (510-q) of the transparent optical shell (510). It is attached to the accommodating cavity (510-q) of the transparent base shell (510B) by a positioning structure, and an air layer is formed between the inner support body (520) and the transparent optical shell (510) above it. A white PCB board is provided on the inner support body (520). The six photovoltaic cells of the photovoltaic device (550) are arranged in a radial, modular pattern around the central axis of the transparent protrusion (510A) on the PCB board with a central empty space. The peripheral LED light source group (540) consists of six SMD-packaged white 2835 LED beads. Each LED is positioned in the space between adjacent photovoltaic cell blocks on the inner support body (520) below the inner ring surface (510B-a2) of the photovoltaic device (550), surrounding the central space formed by the photovoltaic cells. A recessed slot (510k) may also be provided on the inner ring surface (510B-a2) above the LEDs in the peripheral LED light source group (540), serving as a light-diffusing structure to improve the visual comfort of non-motorized vehicle drivers and pedestrians.

[0201] The central LED light source group (530) consists of 6 Lamp-packaged white F5 LED beads. Each LED is divided into two groups (3 beads in each group) facing forward and backward, and is fixed on the upper protrusion of the inner support body (520) in the cavity (510-q) of the transparent protrusion (510A) above the central empty space formed by the photovoltaic cells of the photovoltaic device (550).

[0202] Furthermore, the 12 photovoltaic cells of the photovoltaic device (550) can be arranged in a radial, block-like pattern around the central axis of the transparent protrusion (510A) on the PCB board with a central empty space. The LED of the peripheral LED light source group (540) consists of 12 SMD-packaged white 2835 LED beads. Each LED is positioned in the space between adjacent photovoltaic cell blocks on the PCB board below the inner ring surface (510B-a2) around the central empty space formed by the photovoltaic cells of the photovoltaic device (550). On the inner ring surface (510B-a2) above the LED of the peripheral LED light source group (540), there are also (12 / 2 = 6) slots (510k) spaced apart. The slots (510k) are circular holes. The transparent optical shell (510) is inverted, and a mixture of long-afterglow luminescent powder and transparent epoxy resin is poured into the circular holes and leveled and cured to form (12 / 2) =6) Long-afterglow light emitters (5110), the six SMD-packaged white 2835 LED beads of the peripheral LED light source group (540) below can be controlled to emit light at a certain period and duty cycle to excite the long-afterglow light emitters (5110) to emit afterglow light, while the six SMD-packaged white 2835 LED beads of the peripheral LED light source group (540) above which does not have long-afterglow light emitters can emit light directly from its outer top surface (510A-a) after emission. 1) The light emitting surface (510A-b1) and the outer ring surface (510B-a1) emit light, and the mixture of long afterglow luminescent powder and transparent epoxy resin is poured into the light guide receiving groove (510k) on the top of the transparent protrusion (510A) (located at the top of its receiving cavity when placed upright) to about 3mm and leveled and cured to form a long afterglow luminescent body (5110), which can be excited to emit afterglow light by external light or internal LEDs after refraction and reflection (including total reflection).

[0203] The energy storage element (560) uses a lithium battery, and the control drive circuit (570) uses a single-chip microcomputer control drive circuit. It is embedded under the inner support body (520). The central LED light source group (530), the peripheral LED light source group (540), the photovoltaic device (550), the energy storage element (560), and the control drive circuit (570) are connected to form a circuit by wires. Then, white epoxy resin is poured into the bottom opening of the accommodating cavity (510-q) of the transparent optical shell (510), and it is leveled and cured to form a curing body (580). The inner support body (520), the central LED light source group (530), the photovoltaic device (550), the energy storage element (560), and the control drive circuit (570) are encapsulated in the transparent optical shell (510) to form a waterproof encapsulation structure.

[0204] In this configuration, the main beams (L3) of each LED in the central LED light source group (530) are incident from the inner side (510A-b2) in front of it, refracted, and displaced upwards, then emitted from the outer side (510A-b1) in six directions at an elevation angle of approximately 2° to 12° towards the side front.

[0205] The light beam (L4-1) of the peripheral LED light source group (540) is incident from the inner ring surface (510B-a2) above it, refracted from the outer ring surface (510B-a1), and then emitted to the side front of the LED. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (530) on the same side along the vertical plane of the central axis of symmetry.

[0206] The second LED beam (L4-2) of the peripheral LED light source group (540) is incident from its inner side (510A-b2) on the opposite side, refracted from its outer side (510A-b1), and then emitted towards the side front of its opposite side. The third LED beam (L4-3) of the peripheral LED light source group (540) is incident from its inner top surface (510A-a2), refracted from its outer top surface (510A-a1), and then emitted towards the side upper of its opposite side. The fourth LED beam (L4-4) of the peripheral LED light source group (540) is incident on the inner sides (510A-b2) of the left and right sides of the LED and undergoes total internal reflection before emitting from the opposite side of the LED. The outer surface (510A-b1) refracts the light and then emits it towards the side front of the LED opposite to it. The light beam (L4-5) of the LED of the peripheral LED light source group (540) is incident at the junction of the inner ring surface (510B-a2) and the inner surface (510B-b2) above it. After being reflected by the reflective layer (510B-f) on the outer surface (510B-b1), it is incident again from the inner surface (510A-b2) on the opposite side of the LED and then refracted from the outer surface (510A-b1) and emitted towards the side front of the LED opposite to it. It forms brightness compensation and angle compensation with the light emitted from the central LED light source group (530) on the opposite side along the vertical plane where the central axis of symmetry is located.

[0207] This allows for the formation of a brighter, luminous raised solar-powered underground road stud with a complete 180° luminous elevation range within the vertical plane containing at least the main beam of the central LED light source group (530).

[0208] Furthermore, the peripheral LED light source group (540) contains 6 LEDs arranged at approximately equal intervals around the area between the photovoltaic cells below the peripheral LED light source group (530). The luminous range angle of each LED is greater than 120°. Thus, the LEDs of the peripheral LED light source group (540) compensate for the horizontal luminous range angle of the LEDs of the central LED light source group (530) with their horizontal luminous range angles, thereby forming a brightened, luminous, raised solar buried road stud with 360° luminous coverage around the road stud without any gaps.

[0209] Furthermore, dot-matrix and spoke-shaped light-guiding structures are respectively provided on the outer top surface (510A-a1) of the transparent protrusion (510A) and the outer ring surface (510B-a1) of the transparent base shell (510B), which also have anti-slip function.

[0210] Alternatively, the top outer diameter (Rf) of the transparent base shell (510B) wall can be larger than the bottom outer diameter (Rc) of the transparent base shell (510B) wall. An annular light-guiding groove (510k) is provided at the edge of the outer ring surface (510B-a1) of the transparent base shell (510B). A mixture of long-afterglow luminescent powder and transparent epoxy resin is poured into the annular light-guiding groove (510k) and leveled and cured to form a long-afterglow luminescent body (5110). Figure 26 , 27 As shown.

[0211] Alternatively, the outer wall and bottom of the transparent base shell (510B) may also be fitted with an upward-opening, bottom-filling, encasing-type bottom shell (590), such as... Figure 24 , 25 As shown, the casing-type bottom shell (590) can be a soft cushioning shell (which can provide cushioning) or a hard protective shell (which can provide protection). The bottom of the hard protective shell may have an injection hole.

[0212] This utility model of a brightening and luminous raised solar-powered underground road stud involves embedding the transparent base shell below the outer ring (buried reference surface) into the road edge, lane divider, or center line during installation, while the top of the transparent raised section below the buried reference surface protrudes from the road surface or ground. It primarily utilizes a combination of high and low, inner and outer LED light sources to create a three-dimensional luminous effect, combining points (formed by the relatively concentrated arrangement of the central LED light source) and surfaces (formed by the distributed arrangement of multiple LEDs in the outer LED light source). The outer LED light source compensates for the brightness and angle of the central LED light source, enhancing overall luminous brightness. Combined with long-afterglow luminescent elements, it allows for a larger luminous area for close-range observation, facilitating observation by non-motorized vehicle drivers and pedestrians, and a longer viewing distance for motorized vehicle drivers. Furthermore, it facilitates various controllable luminous effects such as dual-group dual-control and color switching, resulting in significant social and economic benefits.

[0213] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, variations, combinations, additions, equivalent substitutions, etc., made within the spirit and principles of the present utility model, or the application of the present technology to related and similar technical fields, should be included within the protection scope of the present utility model.
